Key benefits:

  • Struvite dissolution: URINARY S/O helps to dissolve all types of struvite stones.
  • Urine dilution: Diluting the urine makes it less liable to form struvite and calcium oxalate stones.
  • Low RSS: Helps to lower the concentration of ions contributing to crystal formation.
  • Protecting bladder mucosa: Glycosaminoglycan (GAG) is a natural part of the bladder mucosa and protects against bacteria and toxins.

Changing your pet's diet and length of treatment:
Your pet will need to stay on this diet for 5 to 12 weeks, or until the stones are dissolved. It is advisable to feed this diet for a further 6 months to prevent a recurrence.
